Sadly, the directors cut of Freaks no longer exists; 30 mins or so were cut after a disastrous test screaming... One woman even threatens to sue MGM claiming that the movie caused her to miscarry!
Whether that's why the version that exists today seems a little oddly passed in the middle is hard to say; many films from that era seem to be missing a middle segment (how did they get King Kong back to New York anyway?) so the jump from flirtation to wedding may possibly have always existed.
What we do know that we are missing is an extended 'revenge' sequence, which originally included a castration!
In any case, Freaks, in it 63 min version was STILL banned in the UK for 30 years!
The most striking thing about the movie, is where it's sympathies lay: dislike it's sensationalist title and tag line ("Can a full sized woman ever truly love a MIDGET?") from the opening crawl the film sides firmly with the eponymous sideshow workers.
